Jerusalem Council decision was a compromise between the Judaizers and Gentile Christians

[TonyChanYT]

Paul and Barnabas were in Antioch in Acts 15:

1 Certain people came down from Judea to Antioch and were teaching the believers: “Unless you are circumcised, according to the custom taught by Moses, you cannot be saved.”

These were Judaizers.

2 This brought Paul and Barnabas into sharp dispute and debate with them. So Paul and Barnabas were appointed, along with some other believers, to go up to Jerusalem to see the apostles and elders about this question.

What happened next was the famous Jerusalem Council. The Judaizers, Peter, Paul, and Barnabas presented their arguments.

Finally, James arrived at a compromise:

[2] from sexual immorality,
[3] from the meat of strangled animals and
[4] from blood.

The council adopted this decision and wrote a letter:

23b they sent the following letter:
The apostles and elders, your brothers,
To the Gentile believers in Antioch, Syria and Cilicia:
Greetings. … 28 It seemed good to the Holy Spirit and to us not to burden you with anything beyond the following requirements: 29You are to
[1] abstain from food sacrificed to idols,
[2] from blood,
[3] from the meat of strangled animals and
[4] from sexual immorality.

Joseph A. Fitzmyer disputes the claim that the Apostolic Decree is based on the Noahide laws (Gen 9) and instead proposes Lev 17–18 as the basis for it[33] (see also Leviticus 18). He also argues that the decision was meant as a practical compromise to help Jewish and Gentile Christians to get along, not a theological statement intended to bind Christians for all time.
